Gelding as a sibling

Gelding as a sibling - My 10 year old gelding is looking for a new home as a sibling because he is lame for unexplained reasons. He was already in clinic and was x-rayed up to the elbow. He comes with me unfortunately too short and it will be more when I go back to work.
He was ridden by me until 2020. He likes to go for walks and loves to be pampered. Small markel he has: he can not be taken from the paddock on some days and then runs away. But with treats and perseverance, this is settled again. He has a passport without pedigree
